Starch and Dry Matter Content in Coloured Flesh Table Potato Tubers

Abstract The study aimed at comparing of basic components of table potato tubers, that is starch and dry matter of seven cultivars with coloured flesh and one cultivar characterised by light flesh. The study material consisted of potato tubers obtained in a one-factor field experiment carried out at the Agricultural Experiment Station in Zawady (52003’N, 22033’E) owned by the University of Siedlce in Poland in 2021–2023. The following cultivars were tested: Eurostar (light yellow flesh), Rote Emmalie and Herbie 26 (red flesh), Provita, Salad Blue, Blaue Annelise, Vitelotte Noire and Bora Valley (purple and blue flesh). The highest average starch and dry matter contents were determined in the tubers of cv. Eurostar with light yellow flesh (respectively 167.6 and 262.1 g kg− 1), and cv. Blaue Annelise with coloured flesh (respectively 118.3 and 211.0 g kg− 1), them being the lowest in red flesh tubers of cv. Rote Emma (respectively 96.0 and 173.8 g kg− 1).
